The invention relates to fluting machines and its general object is to provide an imn proved machine/of that nature having novel means thereon for the support of a material receiving needle. l

In prior constructions, it has'been found difficult to prevent the receiving needle from bending or buckling during the operation of the machine. Inasmuch as these needles are is of considerable length, it has been found quite dillicult to prevent such buckling without impairing the operation of the machine. Thus, a more specific object 'is to produce a machine of thischaracterinvvhichthe receivingneedle is ,supported primarily throughout substantially its entire length, said primary supporting means beingl retractable as the process of fluting goes on, With aV secondary supporting means co-acting to providethe deao sired support' during retraction of said primary means.

In pursuance of the foregoing objects, I aim to provide `a luting machine comprising a pair yof intermeshing toothed rolls andinaterial receiving needles-"positioned With .their points arranged to penetrate 'the material as it is fluted, with means to support the needles up to a point adjacent the rolls, a portion of said supporting meansgbeing retractable as increasing amounts ofniaterial are threaded upon the needle, and another portion of said means being 'arranged to support the'portion of theneedles thus vuncovered and having fluted material thereon.- Y

Further Vobjects and ,advantages Will become apparent from the following description of the preferred form of the invention, as shown in the drawings, in Which Figures 1 and 2 are a plan vievv and a side 4 elevation, respectively, of the preferred embodiment of the invention.

' Fig. 6 is a section on the line 646 of Fig. 1, showing the primary and secondary needle supports.`

`vertically slidable bearing 13.

While I have herein disclosed a preferred embodiment of my invention, it is obvious that it is-susceptible ofvarious modilications and alternative constructions and it is not my lintention to limit the invention to this exact s 13 in parallel relation to each other, With the W" teeth on one roll intermeshing With the teeth on the other. The invention contemplates a series of circumferentially alined slots. or notches V18 through the 4teeth of each roll,

which register to provide apertures 19 (Fie.

3) therebetween in Which the points of needles 2O are positioned so as to penetrate the material as the flutes are formed.

Suitable means 21 for raising and lowering the roll 17 mounted on the shaft 15 in the slidable bearings 13, iyhich in this case is shown as being the upper roll, is provided to permit of adjustment of the rolls. v"I "he'rolls may be driven by a ratchet device 22cm the shaft le operated by a suitable hand lever 23,

the roll 17 being rotated through its meshing engagement With the driven roll.

A suitable table 24 and guide 25 for direct-- ing the material between the rolls may be mounted on one side of the standard 11.

In attaining the major objects of this invention, I prefer to employ an arrangement wherein each needle is supported throughout substantially its entire length, first. by afretractable means and then by a second and independent means adapted to guide and progresssivelyto supplantsaid iirst mentioned means, as the material is fed upon the'needle'. vIn a general Way, the'attainment of this feetiire is achieved bythe employment of tubular members arranged vto surround the needlesV and in turn to be supported oy-a jaw-like arrangement of plates which permits a sliding movement of the members therebetween. As

the tubes move axially and between the plates, i

means are provided thereon which supplant the tubular members in their support of the needles.

While I will, for the purpose of a more concise disclosure, deal with the machine as embodying only one flute receiving needle and the supports therefor, it will be seen from the drawings that the mounting of a plurality of needles is contempla-ted. Each needle is mounted in the manner to be described and may be used either in conjunction with another or alone as the occasion demands.

In the preferred embodiment shown in the drawings a. stationary bed plate 26 is suitably mounted on the base l0, as by the bolts 27, and projects outwardly therefrom in direct alinement with the rolls and .table 24. The bed plate 26 carries spaced vertical supports 28, 29 and 30, also in alinement with the rolls, for the mounting thereon of the needles and needle supporting members.

The primary or initial needle support comprises a stationary elongated member, such as the rod 3l, adapted to abut the needle 20 and a tubular member 32 mounted on said rod for telescopic movement relative thereto and arranged to surround and support said needle when extended from said rod. The rod 3l is mounted in the support 28 most remote from the rolls and extends towards said rolls parallel to the bed plate and base l at a height substantially the same as that of the apertures 19 between the rolls. Slidably mounted on the free end of the rod 3l is the tubular member 32 which passes through suitable openings 33 and 34 in the forward supports 29 and 30. Suitable means such as the collar 35 on the end of the tube 32, is adapted to engage the support 29 to limit the movement of the tube 32 from the rod 3l. Preferably an auxiliary tube guide is provided upon the forward support 30 comprising a plate 36 suitably secured on the support and having an upwardly opening U-shaped slot 37 therein arranged to receive the tube 32. The tube is of such diameter as to telescope snugly upon the rod 3l and is substantially larger than the material re- 'z eeiving needle 20 held therein. The tube and w! pointed end of the needle projecting beyond the end of the tube and resting in the aperture 19, between the rolls. As the material is fed through the rolls, fluted and threaded upon the needle 20, it will be seen that the needle will be held against bending or buckling by the tube 32, which, as the material is forced rearwardly on the needle, will be telescoped rearwardly over the rod 31.

However, as the tube slides rearwardly, the needle is not left unsupported. A secondary reenforcing means is provided which, in this instance, holds the needle through the provision of means adapted to engage the material already threaded upon the needle. To this end a pair of plates 38 a-nd 39 are pivotally mounted at one end upon the support 30 on opposite sides of the opening 34 through which the tube 32 passes. Thus the plates V38 and 39 provide a hinged jaw-like device which when closed extends forwardly along the tube, and when opened, as shown in dotted lines Fig. 2, exposes the tubes. On each side of the support 30 and between these plates, a horizontal rib 40 isl provided to space the plates a correct distance apart as determined by the diameter of the tube. Means for clamping the plates closed is provided at the free ends thereof comprising herein a pivoted clamp 41, on one plate having an arcuate cam slot 42 therein arranged to engage a pin 43 or the like projecting from the other plate. A suitable handle 44.1nay be provided to facilitate manual manipulation of the clamp. By this arrangement the tube 32 will be held between the plates 38 and 39 throughout the major portion of its length with the plates su-liiciently spaced apart by the ribs 40 to' permit the desired sliding movement of the tube therebetween. Any preferred means, such as the stop 45 mounted upon the support 30 is provided as a rest for one plate when they are parted, a suitably resilient pad 46 being positioned on the base as a stop for the other plate.

At spaced intervals 011 one plate pairs of pointed pins 46 are mounted in such manner as to straddle the tubey 32 when the plates 38 and 39 are closed, and registering openings 47 are provided in the opposite plate to receive the pointed ends of the pins therein.

The pins 46 may, if desired, be rigidly mounted in the plate, but I prefer to employ a simple means for removably securing the pins thereon for replacement when necessary. In the present instance, this means comprises a groove-48 formed in the outer side of one of the plates having atone side of the groove a pair of openings 49 through the plate to receiv-e theV needles 46. The opposite side of the groove is formed at an angle to the plate to provide a cam surface 50. A suitably shaped wedge 5lisarranged to lit within the groove withv an' angled surface thereon, adapted when the wedge is forced into the groove by any suitable means as the screws 'i 52 to ride on the comglementary surface of the grooveand bind the outer ends of the pins 46 against the opposite' surface of the groove.. n

In this manner a secondary needle supporting means is provided which, as thc tube 32 is retracted during the process of feeding the material upon the needle, will. engage the material thereabout to prevent any bendingor buckling of the needle( Y i' The operation of the machine is exceedingly simple and ellicient. VThe material vis guided into the rolls 16 and 17 from the table eration of the hand ratchet Q2. As the material is fluted by the toothed rolls each fold is pierced by the needles 20 and is pushed rearwardly thereon. As material accumulates upon the needles and bears upon the ends of the needle supporting tubes 32 the tubes will be forced rearwardly between the hinged plates 38 and 39, which, of course, are closed. When the tubes have been retracted to the free edge of the plates and the material has become packed upon the needleV being parted and the material distributedV along the needles as often as is necessary. After completion of the process the needles together with the materialrthereon are removed from the machine, the tubes 32 being then entirely retracted and the plates 38 and 39 being parted so as to permit such removal. The material may then be withdrawn onto threads in the usual manner.
